This is doable + breaks the following.

1) Container data no longer secure.

2) You can no longer use any operations like move or copy.

Best explain what you're trying to accomplish by having data at host level
then running container level database instance.

Better to run both at one level, either both at machine level or both
at container level.

If you do this, likely you'll have ongoing problems, including... if you
ever accidentally install server level database instance, you'll likely
destroy your data beyond any recovery.
